Specification of Letters Patent.

Application filed August 4, 1919. .Serial, No. 815,103.

1 '0 all '21: 7mm it may concern 7 Be it known that I, CLARENCE E. Anusmm, a citizen of the United States of America, residing at Talladega, in the county of 'lalladega and State of Alabamzn have invented certain new and useful Improvements in (coking-Stoves; of which the following is a specification. v

The present invention relates to means for cooking and provides for the use of the least amount of heat necessary to cook with.

The invention further provides for the use of an adjustable oven which may be adjusted to conform to the size of the article to be cooked, whether a very large dinner or a very small pie, thus utilizing only the amount of heat space necessary to cook various articles. v

The invention further provides for the elimination of heating unused space in an oven where nothing is being cooked, thus saving heat and gas, 'orother fuel.

The invention further rovides in the adjustable oven, space su cientto cook an extra large dinner, or an amount offood at one time. doing away with two separate bakings, allowing a very largebaked meal to be-served from the oven hotrwithout al lowing previous cooked articles to get cold.

before serving.

The invention further rovides for the use of an adjustable warming closet, heated either from the regular cooking top or baking oven. I

The invention further provides for an ad jnstable burner to be adjusted to the articlev containing food to be cooked.

The invention further provides for food. vessels that set down in a recess, forming a wall around the. said vessels, but .spaced .0 the heat from lithelburncr for the p n-pom of apart a" distance' for 1 the upward p conforming tozan'd-forcing the passage of the heat a sels. 7-

The invention further irovides a kitchen hcatcr,- by inclosing the container walls as a radiatonto-utilize theheat passing through the wallsf' for heating the kitchen in wintenj -The air intake and air outlet in the ldtchenhcater opening into the kitchen can be closed-in summer and the lost heat sent through the vent pipeiby openng the vertical wall of the vesing outlet in the top of kitchen heater, giving a cool kitchen. ,All outlets intlie kitchen heater can be closed, a dead air space which forms a heat insulation, which action causes a small amount of lost heat to pass through the vessel container walls and the heat is then forced along the food container to heat same and into the vent pipe.

The invention especially provides for an Patented Mar. 8, 1921.

adjustable burner, which automatically at all times adjusts itself to the bottom of a food container any distance down in the burner compartment and has a normal position at the cooking top;

In the drawings forming a part of this specification I have shown the invention in the forms I consider the best, however the invention can be, embodied in other forms and with the appended claims I intend to cover the invention in any form in which it can be embodied.

In the accompanying drawings part of this invention,

Figure 1 is a side elevation of the cooking stove. 4

forming a Fig. 3 is a horizontal cross section of the adjustable oven showing also a plan view of the cooking top taken on the line 3--3 of Fig. 2. 4 ig. 4 is a vertical cross section of a part of the cooking top, showing the adjustable burner and the burner compartment.

Fig. 5 is a vertical cross section of a part of the adjustable oven to show certain parts taken on the'line 5-5 of Fig. 3.

Figf'6; is. a part vertical cross section of a modifiedform of the adjustable oven, showing single sidewalls formed with the samefovenfto as shown Fig. 2 the. inner we 13 as shown in Fig. 2 are not jam; only using the outer side oven alls with the oven racks thereon. formin'gfa single side wall oven instead ofa double/side wall oven.

Similar reference numerals refer to similar parts throughout the drawings.

The cooking stove is formed with an oven body 1 (Figs. 1 and 2) around the back and two sidesfwith a wall 57 at thefront forming the ovenopenings when a single lined oven is used.-when a double lined oven is used the heat resisting material 2 and inner lining 3 are formed with the outer body 1 Formed inside of the stationary oven body is the adjustable or removable oven top i, which can be made alone'or with a single side casing 5 (Fig. 6), however the tween. A heat referred form is shown with an inner casmg 6 (Fig. 2) spaced apart from the outer casing forming heat passa 7 and 8 bear to 7 and 8 can be formed at the back of the oven 4 but it is not nry, only adding to the manufacturing cost, and is herein not shown in i 1',- at 29 and as the "movemfint the lever24isatooth26toengage at an desired tooth27, formed in a late 28 the preferred form.

Oven casings 5 and 6 are preferably secured together with the top 4 by-a brace 16, which brace is formed to-close the ends of the space, forming a'heat retardm chamber 9 above the oven interior 10. eat passages 7 and 8 are closed at the top by wall sup rting braces 14 and 15 and left open at t eir bottoms at 12 and 13.

The inner oven casing. 6 has heat inlets and outlets 48, 49, 50. 51 and 52 formed in the side walls 6 and heat outlets 53 the top thereof into chamber 9, which Wlll be later described. The outer oven casing 5 has heat outlets 54 formed in the top thereof.

The oven 4 is supported by rods 17 and 18 pivoted to the side walls thereof, which rods are pivoted to arms 18' and 19, secured to a shaft 20 which is mounted in bearings 21 and 22 at each end. The shaft 20 extends 1 throligh the oven body 1 through a flange 23 ig. 3) andv has mounted on the end thereof a hand operating lever 24 with a handle 25 at its end. Preferably formed on and rest whi ,is seeunedto the wall of y 1,

the medium of handle 25, lever 24,'shaf t fll"arms 19 and 18, rods 17 and 18,

it a desired the body of even interior'10, which movement forms .anad'udable-warming closet 11 between the top 0 oven 4 anditop of body 1. The same movement also spaces the top of the oven interior 10 from the oven bottom 31 any desired distance which forms an adjustable '38 and 39 for the which walls are formed a distance to permit of the ent at all times of one of the racks 46in each, to at all times close the openings made between the bottom 31 and wall 6, which openings permit the movement oven-*4 has a vertical move-- escape up or down of the oven racks 46. The continued closing of these openings along walls 44 and45 forces the heat from the burners 47, to pass through the openings 49, 50, 51,-

52 or into openings 12 and 13, which may be in registration with the level of the burner 47, into the heat passages 7 and 8,

that the heat may rise-in these passages and enter the oven at the top, to insure a baking oven hotter at the top in oven 10, that at the bottom 31, to obtain better baking.

It is readily seen, Fig. 2, that the oven heat openings 48, 49, 50, 51, 52 and openings 12 and 13, are arranged to permit of the entrance of the heat into the oven 10, and to receive through said openings the heat from i the burners 47 at whatever place the operator may set thedesired baking space of oven 10 at the distance between the moving spaces 29 and 30. The burners are individually operated with valves 63 and 64 formed on a manifold 65.

The circulation of the oven is secured with air openings 56 in the bottom plate 35 for air to the burners and circulation, passing through the described adjustable oven opening into oven 10, through outlets 53 into chamber 9, through outlets 54 into the warming closet 11, and finally out vent pipe 55. The adjustable oven in formed to have an opening in the front part (Figs. 1 and 3), formed with sides 59 and top 58, which permit of the use of placing food to be cooked therein, which opening is in registration with a similar-opening in wall 57, which opening closedwith one or more doors. The doors are formed in a manner that either the top door 60 or the lower door 62, may be opened independent of each other as desired, with a. hinged brace6l formed to rest under the door flanges to prevent the of heat and to be either opened or left closed.

When the adjustable oven'is being used high up, the opening of the doors 60 and 62 and hinged brace 61 at once give a large opening the full size of the oven with nothing in the way of takingfood out or putting same in. The lower door 42 permits entrance to broiler oven before described.

The cooking top 70 (Fig. 2) may be formed with the'open grate top but it is herein shown with the preferred closed top with a largeopening 71, regplar openings 72 and simmer openings 73, ich are closed with lids when not in use.

The object of the adjustable burner with its associated parts is to confine and utilize as much heat as possible with a circulating heat, therefore the use of the closed top is preferred. Formed underneath and near the top 70 and secured to stove wall 106 is v a horizontal 'wall 74, which forms a shallow heat circulating chamber 7 5 for the purpose of confining the heat to the top 70, having a vent outlet 101, in wall 106, through vent pipe 102 to vent 55. The vent 102 in this form of the invention is shown entering the warming closet at opening 103 therein for the purpose of having a heated warming closet from the top burners when the oven .is not in use, before passing heat in vent 55.

Formed below the outlets 71 and 72 in top 70 (Figs. 2 and 4), are curvilinear formed burner compartments 76, with a heat outlet 7 7 at the top and an opening 78 at the bottom for the purpose of removing the burners 82 for cleanin by removing pla e 79,-with air inlets 80, by fasteners 81 from lower wall 35. A dri pan (not shown) may be installed below tiie plate 79. Movably mounted within the curvilinear formed walls 7 6 are the adjustable burners 82, which are secured to a plate 84, which plate is pivoted to a rod 85, which rod is pivoted to an arm 87 at one end extending through slot 86 'in wall 76, with a weight 90 at its other end and movably secured in a bearing to a brace 88 secured to the lowerwall 35. The burner has secured thereto guide arms 37 for the purpose of holding the burner in a horizontal plane as they frictionally engage the side walls of the compartment 7 6, as the burner is moved up or down, through the medium of a cooking utensil bottom engaging the burner lugs 92, to operate the burner position. The burner lugs 92 are the distance necessary-for complete combustion from the gas holes in burner to the cooking utensil bottom.

Connected to the burners 82, is a flexible gas tubing 83, preferably metallic, which is of sufiicient length to allow for the movement of the burner from top to bottom of wall 76, and is connected to each individual gas controlling valve on the manifold 65 for operation. A lug 89 secured to the brace 88 engages the arm 87 to prevent the passage of the burner lugs 92 above the top 70 when an open top is used, however when the solid 'top is used, the top ends of guide arms 37 engaging the top 7 0 serve this purpose. The

adjustable burner is formed to have an automatic movement by having the weight of part 90 secured to the lever arm 87 greater than the burnerwith its accessories, thus the burner will automatically stay at the cooking top in position for frying or other cooking as shown by pan 104, when.burner is not moved downward, and will always retain a position en aging the bottom of any depth kettle any depth down in the burner compartment 76, as shown by. 'diflerent depth kettles 95. The cooking utensil 95 is formed with a handle 105, or similar handle, for removing or placing same down into the burner compartment 76, with a kettle flange 107 closing" :t lie opening 71 or 72 of top 70 to permit '1i. escape of heat. The vertical wall of the compai tn ent 76 is spaced a disa radiator or kitchen heater and are preferably used with radiator flanges 96 secured thereto, to utilize the heat passing into the compartment .97. This compartment 97 formed by walls 74, 35 and 106 with the compartments 76 formed therein. can be utilized in three diflerent ways.

- In winter months the cold air inlet 98 permits the air to enter for heating and is sent out hot through hot air outlets 99 for kitchen heating.

In summer months the inlet 98 is left open and the outlet 99 is closed, the outlet cap 100 formed in the wall 74 is removed, thus the hotair has outlet access to help heat the cooking top into space 7 5 to vent The openings 98, 99 and 1.00 may all be closed to form a dead air space which forms an insulation, the heat passing through compartment walls 76 is then minimized and is forced on cooking utensils like 95.

' y In a modified form of my invention, Fig.

6 is a part vertical cross section of a modified .form of the adjustable oven formed with a single side wall'5- spaced away for entrance of heat at 44 from the oven bottom 31. The operating of this form is the same as the preferred form. I
